ABSTRACT

This study aimed to obtain the proper solvent for extracting bioactive compounds from Artemisa ifranensis J. Didier. Moreover, the total phenolic, flavonoid contents, and the antioxidant activities of Artemisia ifranensis leaves extracts from Morocco were evaluated. The total phenol and flavonoids contents from various extracts of the vegetal specie were determined by using Folin-Ciocalteu and AlCl3 assays respectively. The results showed that ethyl acetate extract of exhibited the highest phytochemical composition (total phenolic content 35,81 milligrams of gallic acid equivalent/ gram of Extract (mg GAE/g), total flavonoids content 31,85 milligrams of Quercitin/grame of Extract (mg QE/g). Thereafter, the antioxidant activity of extracts was evaluated by the capacity of free radical trapping DPPH• (1,1-Diphenyl-2- picrylhydrazyl). The results reported that the scavenger power of phenolic extracts compared to the standard antioxidant was efficient and showed potential antioxidant properties. Similarly, the best antioxidant capacity was on served in ethyl acetate extract; it has generally the lowest value IC50= 0,656 mg/ml. Data from current results revealed that this plant act as a valuable source of antioxidants.
